Description

【０００１】
【発明の属する技術分野】
本発明は、建具や家具の引き戸に使用される戸車装置に関するものであり、車輪の位置調節が可能な戸車装置に関するものである。
【０００２】
【従来の技術】
建具や家具の引き戸の下端部には、引き戸の移動を容易にするために戸車装置が取り付けられる。旧来の戸車装置は、単に車輪をネジ等で固定するものに過ぎなかったが、近年、レールに対する位置合わせを容易にするために、引き戸に取り付けた状態で車輪の位置を調整することができるものが知られている（特開平９−６０３９９号他）。
例えば特開平９−６０３９９号に開示された戸車装置は、カムを使用して車輪を左右方向（車輪の走行方向に対して左右以下同じ）に移動させることができる。すなわち特開平９−６０３９９号に開示された戸車装置では、外ケースから露出した操作部を回転してカムを回動させ、車輪を左右方向に移動させる。
【０００３】
【発明が解決しようとする課題】
前記した様に、引き戸に取り付けた状態で車輪の位置を調整することができる戸車装置が知られているが、従来技術の構成は、いずれも車輪の移動量に対する操作部の操作しろが小さく、左右移動の微調整が困難であるという不満がある。
すなわち実際上、引き戸に取り付けた車輪の位置が、レール等の軌道から大きく外れていることは無いので、施工現場において戸車装置の車輪を移動させなければならない量は、１ｍｍ程度である。
これに対して従来技術の戸車装置では、ドライバー等によって操作部を９０°程度回動させただけで、車輪は左右方向の移動しろの全域に渡って移動してしまう。そのため従来技術の戸車装置は、ドライバー等をほんの少し回しただけで車輪が大きく移動し、ドライバー等の回転量が僅かであるために微調整がしづらい。
そこで本発明は、従来技術の上記した問題点に注目し、車輪を左右方向に移動させる際の操作部の操作量が大きく、微調整が容易である戸車装置の開発を課題とするものである。
【０００４】
【課題を解決するための手段】
そして上記した課題を解決するための請求項１に記載の発明は、車輪を有し、当該車輪の位置を、車輪の走行方向に対して左右方向に移動させる左右移動機能を有する戸車装置において、ケース部材と、ケース部材に対して相対的に移動可能であり、車輪と左右方向に一体的に移動する左右移動部材と、ケース部材に対して左右方向の移動が規制された駒部材と、駒部材を車輪の走行方向に移動させる駒移動手段を有し、左右移動部材はコの字状であり、左右移動部材は天部及び底部を有し、駒部材の上面と下面は、天部と底部に挟まれて摺動し、前記駒部材の上面及び下面と左右移動部材は傾斜面を介して係合し、駒移動手段によって駒部材を車輪の走行方向に移動させることによって左右移動部材が左右に移動し、車輪が左右に移動することを特徴とする戸車装置である。
【０００５】
本発明の戸車装置では、左右方向への移動が規制された駒部材を持ち、当該駒部材は左右移動部材と傾斜面を介して係合している。また駒部材を車輪の走行方向に移動させる駒移動手段を備える。そのため駒部材を駒移動手段によって車輪の走行方向に移動させると、駒部材に対して傾斜面を介して係合する左右移動部材が走行方向に対して左右に移動する。
本発明の戸車装置では、駒部材の車輪走行方向への移動を傾斜面によって左右方向への移動に変換して左右移動部材を移動させ、車輪を左右に移動させるものであるから、ドライバー等の操作量が大きく、微調整が容易である。
本発明の戸車装置では、駒部材は、上下方向にも自由度を持たず、車輪の走行方向に沿った方向にのみ移動可能である。
【０００６】
また請求項２に記載の発明は、駒部材又は左右移動部材の一方は、水平となる面に車輪の走行方向に対して傾斜する溝を有し、駒部材又は左右移動部材の他方には前記溝と係合する突起部が設けられていることを特徴とする請求項１に記載の戸車装置である。
【０００７】
本発明の戸車装置では、傾斜する溝は、水平となる面に設けられているので、駒部材が車輪走行方向に移動することにより、左右移動部材は左右方向に移動する。また駒部材又は左右移動部材の一方には溝が設けられ、他方にはこの溝と係合する突起部が設けられているので、駒部材と左右移動部材の相対動作は、確動的であり、駒部材の位置と左右移動部材の位置は、１対１に対応する。そのため駒部材を操作することにより、左右移動部材を左右いずれの方向にも移動させることができる。
【０００８】
また請求項３に記載の発明は、左右移動部材は水平かつ平行な二平面を有し、駒部材は前記二平面の間に挟まれて摺動し、駒部材の摺動面又は左右移動部材の前記二平面のいずれかに車輪の走行方向に対して傾斜する溝を有し、他方に前記溝と係合する突起部が設けられていることを特徴とする請求項１に記載の戸車装置である。
【０００９】
本発明の戸車装置についても傾斜する溝は、水平となる面に設けられているので、駒部材が車輪走行方向に移動することにより、左右移動部材は左右方向に移動する。また駒部材又は左右移動部材の一方には溝が設けられ、他方にはこの溝と係合する突起部が設けられているので、駒部材と左右移動部材の相対動作は、確動的である。特に本発明の戸車装置は、左右移動部材が水平かつ平行な二平面を持ち、駒部材はこの二平面の間に挟まれて摺動するので、動作が確実である。
【００１０】
また請求項４に記載の発明は、駒移動手段はネジであることを特徴とする請求項１乃至３のいずれかに記載の戸車装置である。
【００１１】
本発明の戸車装置では、駒移動手段にネジを採用し、ネジを回転操作することにより、駒部材を直線移動させる。そのため駒部材の移動量に対して、操作量を大きくとることができる。本発明の戸車装置は、傾斜の作用による操作量増大機能とネジによる操作量増大機能が相まって、より大きな操作量を確保することができる。
【００１２】
また請求項５に記載の発明は、車輪を回転可能に保持する車輪保持部材を備え、車輪保持部材は、左右移動部材に対して揺動可能であり、ケース部材には車輪の走行方向に移動する前後移動部材が設けられ、前後移動部材が車輪保持部材の一部と係合し、前後移動部材の移動に応じて車輪保持部材が揺動し、車輪の高さが変化することを特徴とする請求項１乃至４のいずれかに記載の戸車装置である。
【００１３】
本発明の戸車装置では、車輪が左右移動部材に対して揺動可能であり、さらに前後移動部材が車輪保持部材の一部と係合している。そのため本発明の戸車装置では、前後移動部材を移動させることにより、車輪保持部材が揺動し、車輪の高さを変化させることができる。
【００１４】
【発明の実施の形態】
以下さらに本発明の実施形態について説明する。なお以下の説明においては、上下の関係は戸車装置を引き戸に取り付けた状態を基準とする。また各部の動作を説明する際には、車輪の走行方向を基準とする。
図１は、本発明の実施形態の戸車装置の正面図、側面図、平面図及び底面図である。図２は、図１の戸車装置の分解斜視図である。図３は、図１の戸車装置の左右移動部材及び駒部材の詳細断面図である。図４は、図１の戸車装置の正面断面図であり、上下方向へ移動する状態を示す。図５は、図１の戸車装置の平面断面図であり、左右方向へ移動する状態を示す。
【００１５】
各図において、１は本発明の実施形態の戸車装置を示す。本実施形態の戸車装置１は、ケース部材２と、車輪３、車輪保持部材５、左右移動部材６、駒部材７及び前後移動部材８によって構成されている。
【００１６】
ケース部材２は、樹脂の射出成形によって作られたものであり、略四角形をしており、底面の全部と正面及び背面の一部が開放された箱体である。すなわちケース部材２は、図１を基準として（図２は、作図上の都合から左右が入れ代わっている）正面壁１０、操作側側面壁１１、奥側側面壁１２、天面壁１３及び裏面壁１５を有し、内部は空洞部１７となっている。また底面は開放されている。さらに正面壁１０と裏面壁１５の角の部分は円弧状に切り欠かれている。
天面壁１３は、円弧状をしている。また天面壁１３には、円弧面に沿って複数の溝１６が刻まれている。当該溝１６は、全体の剛性を高める機能や成型時の引けを防ぐことを目的として設けられたものである。
【００１７】
ケース部材２の内部の様子は、図４の通りである。すなわちケース部材２の上部には、図４の様に操作側側面壁１１と奥側側面壁１２間を貫通する取付け孔１８が設けられている。そして取付け孔１８の操作側側面壁１１側には、座繰り部１９が形成されている。
【００１８】
またケース部材２の中間部にも貫通孔２０が設けられている。貫通孔２０の操作側側面壁１１側には座繰り部２１が設けられている。
貫通孔２０の中間部は、図４の様に空洞部１７と連通している。すなわち貫通孔２０は、操作側側面壁１１と奥側側面壁１２間を貫通しているが、全体が完全な孔ではなく、中間部の下側は底面側に開放されている。また特に貫通孔２０の中心部は、上部側にも空隙部２２がある。言い換えると、貫通孔２０は、操作側側面壁１１と奥側側面壁１２の近傍だけが完全な孔状であり、他の部位はいずれかの部分が開放されている。
貫通孔２０の操作側側面壁１１の近傍は、溝状であり当該溝状部２４は、図１の様に正面壁１０から裏面壁１５側に貫通している。
【００１９】
またケース部材２の操作側側面壁１１の中心よりも下部の位置には、孔２５と長孔２６が設けられている。孔２５及び長孔２６は、いずれも内部の空洞部１７と外部とを連通するものである。
【００２０】
ケース部材２の操作側側面壁１１に注目すると、前記した様に上部に取付け孔１８の開口があり、その下部に貫通孔２０の開口があり、さらにその下部に孔２５及び長孔２６が順次形成されている（図１ｃ参照）。
そして貫通孔２０の近傍には、矢印と共に「上下」の文字が刻まれ、孔２５の近傍には、矢印と共に「左右」の文字が刻まれている。
またケース部材２の正面壁１０及び裏面壁１５の下部であって操作側側面壁１１寄りの位置には、孔３０が設けられている。
【００２１】
車輪３は、公知のそれと同一であり、車輪保持部材５にピン３２によって回転可能に支持されている。
【００２２】
車輪保持部材５は、鋼板をプレスして作られたものであり、車輪３の両側を跨ぐと共に、車輪３の約４分の１を覆うフォーク部３１を備えている。すなわち車輪保持部材５は、正面側フォーク壁３５ａと、裏面側フォーク壁３５ｂを持ち、両者は渡り部３７で接続されている。渡り部３７は段状であり、ケース部材２に取り付けられた状態を基準として車輪３の上部に位置する部位は、高さが高く、車輪３から外れる部位は高さが低い。そして両者の境界部分には切り込み部３８が設けられている。
またケース部材２に取り付けられた状態を基準として、車輪３の中心と略同一の高さの位置に、揺動支持孔３３が設けられている。
【００２３】
左右移動部材６は、アルミ又は亜鉛ダイカストによって作られた部材であり、その幅ｗ（図３）は、前記したケース部材２の空隙部１７の幅よりも小さい。左右移動部材６は、図２，３の様な複雑な形状をしている。すなわち左右移動部材６は、全体形状が「コ」の字状であり、溝部４０が設けられている。溝部４０は、操作側側面壁１１側の部位が開放されている。また溝部４０は、正面側から裏面側に貫通する。すなわち車輪３の走行方向に対して左右方向に貫通する。
【００２４】
溝部４０の位置はケース部材２に取り付けられた状態を基準として、図２，３の様に中心線から上部端にわたる部位である。すなわち左右移動部材６の溝部４０は、天部４１、底部４３及び奥部４５を有する。天部４１、底部４３は、ケース部材２に取り付けられた状態を基準として、水平かつ平行な二平面を形成する。そして当該水平かつ平行な二平面たる天部４１及び底部４３には、リブ状の突起部５０，５１が設けられている。突起部５０，５１は、いずれも斜め方向にのびている。すなわち突起部５０，５１は、溝部４０の天部４１及び底部４３に設けられ、開口部側から奥側に向かって４５°に傾斜してのびている。
溝部４０を構成する奥部４５には、さらに凹部５２が設けられている。
【００２５】
左右移動部材６の細部を説明すると、左右移動部材６の天面であって溝部４０の開口側の位置には、溝部４０の開口部と平行に段部５３が設けられている。また溝部４０が形成されていない部位は、全体的に肉厚が薄く作られている。そして当該薄肉部５５であって溝部４０よりも高さの低い位置に溝部４０と平行方向に貫通孔５６が設けられている。前記した溝部４０の下部には、溝部４０と平行に小さい溝５７が設けられ、その中心に円柱状の突起６０が設けられている。
【００２６】
次に駒部材７について説明する。駒部材７は、図２，３に示すように長方形の板状であり、その幅Ｗは、前記したケース部材２の空隙部１７の幅に等しく、左右移動部材６の幅ｗよりも広い。
駒部材７には、中心部にネジ孔７０が設けられている。駒部材７の上面６３と下面６５は、ケース部材２に取り付けられた状態を基準として、水平かつ平行な二平面を形成する。そして駒部材７の上面６３と下面６５には、ネジ孔７０の軸方向に対して斜め４５°にのびる溝６７，６８が形成されている。溝６７，６８の幅は、前記した左右移動部材６の突起部５０，５１と合致する。
【００２７】
前後移動部材８は、長尺のネジ７２とこれに係合する板体状のナット７３によって構成されている。
【００２８】
次に本実施形態の戸車装置１の各部材同士の組み立て構造について説明する。本実施形態の戸車装置１では、ケース部材２の内部に上記した各部材が組み込まれている。すなわち前後移動部材８はネジ７２がケース部材２の貫通孔２０に挿通され、先端側が奥側側面壁１２部の孔に支持され、頭部（ドライバーが係合する部位）７５は、操作側側面壁１１の座繰り部２１に支持されている。そして頭部７５の一部が、溝状部２４と係合している。そのためネジ７２は、ケース部材２に対して回転可能であるが軸方向には移動しない。
またネジ７２と係合するナット７３は、ケース部材２の空隙部１７に露出する。そしてナット７３は、その一部がケース部材２の内面と係合し、回転が規制されている。そのためネジ７２を回転させると、ナット７３は、軸方向にのみ移動する。
【００２９】
左右移動部材６は、段部５３がケース部材２の内側の一部と係合し、さらに突起６０がケース部材２の長孔２６に挿入された状態で、ケース部材２の空隙部１７内に挿入される。さらに左右移動部材６に車輪保持部材（車輪３を含む）５が装着され、ピン７７がケース部材２の孔３０、車輪保持部材５の孔３３及び左右移動部材６の孔５６を連通している。その結果、左右移動部材６は、車輪３の走行方向に対して左右方向にのみ自由度を持ち、車輪３の前後方向、車輪３の走行方向の移動が規制される。
【００３０】
また車輪３は、左右移動部材６の移動に伴って、車輪３の走行方向に対して左右方向に自由度を持つ。さらに車輪保持部材（車輪３を含む）５は、ただ一本のピン７７によって左右移動部材６に取り付けられているから、ピン７７を中心として揺動する。
【００３１】
また車輪保持部材５の切り込み部３８には、前後移動部材８のナット７３が嵌合している。
【００３２】
駒部材７は、左右移動部材６の溝部４０に装着され、駒部材７の上面６３と下面６５に設けられた溝６７，６８に、左右移動部材６の溝部４０が係合している。ここで駒部材７の溝６７，６８及び左右移動部材６のリブ状の突起部５０，５１は、いずれも車輪３の走行方向に対して傾斜しているので、駒部材７と左右移動部材６は、互いに傾斜面８８，８９を介して係合している。
【００３３】
駒部材７の幅は、前記した様にケース部材２の空隙部１７の幅と等しいので、駒部材７は、左右方向（車輪３の走行方向を基準）の自由度を持たない。また駒部材７は、左右移動部材６の溝部４０に装着され、左右移動部材６の水平かつ平行な二平面に挟まれて摺動する。そのため駒部材７は、上下方向にも自由度を持たず、車輪３の走行方向に沿った方向にのみ移動可能である。
【００３４】
そして駒部材７のネジ孔７０には、ネジ８０が挿通されている。ネジ８０は、図４の様にケース部材２の孔２５に回転自在且つ軸方向には一体的に取り付けられている。またネジ８０の頭部８１と、駒部材７との間には、座金８２及びバネ８３が介在されており、駒部材７は常時、車輪３側に押圧されている。
【００３５】
次に、本実施形態の戸車装置１の機能について説明する。本実施形態の戸車装置１は、図示しない引き戸の下部に取り付けられる。すなわち引き戸の下部に切り込み部が形成され、図４の様に操作側側面壁１１側から、取付け孔１８に木ねじ８５が挿通されて引き戸に固定される。したがって本実施形態の戸車装置１では、引き戸に取り付けられた状態において、戸車装置１の操作側側面壁１１が引き戸の端面に露出する。そのため本実施形態の戸車装置１では、引き戸に取り付けられた状態において、操作側側面壁１１から露出する前後移動部材８のネジ７２と、駒部材７に挿通されたネジ８０を操作することができる。
【００３６】
そして本実施形態の戸車装置１では、前後移動部材８のネジ７２を操作することにより、車輪３を上下に昇降させ、車輪の高さを変更することができる。すなわち車輪３を降下して引き戸を上昇させる場合は、図４（ａ）の様な状態から、ネジ７２を図１（ｃ）に記載された「上」方向（左回転）に回転させる。その結果、ナット７３が図面左側に移動し、車輪支持部５の切り込み部３８を図面左側に押し、車輪支持部５をピン７７を中心として下向きに傾斜させる。その結果、車輪３のケース部材２からの露出量が増大し、車輪３が下方向に移動する。また車輪３の降下に伴い、引き戸は上昇する。
【００３７】
さらに本実施形態の戸車装置１では、駒部材７に挿通されたネジ８０を回転することにより、車輪３を走行方向に対して左右に移動させ、引き戸を右左に移動させることができる。
すなわち本実施形態の戸車装置１を、図５（ａ）の様な状態から車輪３を図５（ａ）の様に右方向に移動させ、引き戸を左側に寄せる場合は、ネジ８０を図１（ｃ）に記載された「左」方向に回転させる。ここでネジ８０と係合する駒部材７は、その幅がケース部材２の内面の幅と等しく、且つ左右移動部材６の溝部４０に挟まれていて上下や回転方向の運動が規制されているので、駒部材７は、図５（ｂ）の様にネジ８０の頭部側（操作側側面壁１１側）に引き寄せられる。一方、駒部材７に設けられた溝６７，６８は、左右移動部材６の溝部４０と傾斜面８８，８９を介して係合しているので、左右移動部材６は、傾斜面８８，８９に沿って横方向（車輪３の走行方向を基準）に移動する。
【００３８】
ここで、本実施形態の戸車装置１では、ネジ８０によって駒部材７を推進させるので、ネジ８０の回転操作量に対する駒部材７の移動量は僅かである。さらに本実施形態の戸車装置１では、駒部材７と左右移動部材６は、傾斜面８８，８９を介して係合しているので、駒部材７の移動に対する左右移動部材６の移動は僅かである。したがって本実施形態の戸車装置１では、ネジ８０の作用による移動量の縮小と、傾斜面による移動量の縮小の相乗効果により、ネジ８０の回転量を確保することができる。すなわち本実施形態の戸車装置１では、車輪３を左右方向に動かす際に、ネジ８０の回転しろが大きい。そのため本実施形態の戸車装置１は、車輪３の左右方向の微調整を行うことができる。また車輪３の移動量に対するネジ８０の操作量が大きいので、車輪３を移動させる際、ネジ８０の回転に要する力は軽い。そのため本実施形態の戸車装置１は、車輪３の左右方向の微調整を容易に行うことができる。
【００３９】
以上説明した実施形態では、駒部材７に溝を設け、左右移動部材６に突起部を設けたが、駒部材７に突起を設け、左右移動部材６に溝を設けてもよい。
【００４０】
【発明の効果】
以上説明した様に、本発明の戸車装置は、傾斜面を利用して車輪を横方向に移動させるので、車輪の位置決めを容易に行うことができる効果がある。
【００４１】
特に請求項２，３に記載の戸車装置では、駒部材と左右移動部材の相対動作が確動的となり、車輪を左右いずれの方向にも移動させることができる。
【００４２】
また請求項４に記載の戸車装置では、駒移動手段にネジを採用し、ネジを回転操作することにより、駒部材を直線移動させる。そのため駒部材の移動量に対して、操作量を大きくとることができる。本発明の戸車装置は、傾斜の作用による操作量増大機能とネジによる操作量増大機能が相まって、より大きな操作量を確保することができる。そのため車輪の左右方向の位置調節が極めて容易となる。
【００４３】
また請求項５に記載の戸車装置では、車輪の高さについても調節することができる。

[0027]
The front-rear moving member 8 is composed of a long screw 72 and a plate-like nut 73 engaged therewith.
[0028]
Next, the assembly structure of the members of the door machine 1 of the present embodiment will be described. In the door cart device 1 of the present embodiment, each member described above is incorporated in the case member 2. That is, the forward / backward moving member 8 has a screw 72 inserted through the through-hole 20 of the case member 2, a tip end side supported by a hole in the back side wall 12, and a head (part where the driver engages) 75 The wall 11 is supported by the counterbore 21. A part of the head 75 is engaged with the groove-like portion 24. Therefore, the screw 72 can rotate with respect to the case member 2 but does not move in the axial direction.
Further, the nut 73 engaged with the screw 72 is exposed in the gap portion 17 of the case member 2. A part of the nut 73 engages with the inner surface of the case member 2 and its rotation is restricted. Therefore, when the screw 72 is rotated, the nut 73 moves only in the axial direction.
[0029]
The left and right moving member 6 has the stepped portion 53 engaged with a part of the inside of the case member 2 and the protrusion 60 is inserted into the long hole 26 of the case member 2 in the gap portion 17 of the case member 2. Inserted. Further, a wheel holding member (including the wheel 3) 5 is mounted on the left and right moving member 6, and a pin 77 communicates the hole 30 of the case member 2, the hole 33 of the wheel holding member 5 and the hole 56 of the left and right moving member 6. . As a result, the left-right moving member 6 has a degree of freedom only in the left-right direction with respect to the traveling direction of the wheel 3, and movement in the front-rear direction of the wheel 3 and the traveling direction of the wheel 3 is restricted.
[0030]
The wheel 3 has a degree of freedom in the left-right direction with respect to the traveling direction of the wheel 3 as the left-right moving member 6 moves. Furthermore, since the wheel holding member (including the wheel 3) 5 is attached to the left and right moving member 6 by only one pin 77, it swings around the pin 77.
[0031]
Further, the nut 73 of the forward / backward moving member 8 is fitted in the cut portion 38 of the wheel holding member 5.
[0032]
The piece member 7 is attached to the groove portion 40 of the left and right moving member 6, and the groove portion 40 of the left and right moving member 6 is engaged with grooves 67 and 68 provided on the upper surface 63 and the lower surface 65 of the piece member 7. Here, since the grooves 67 and 68 of the piece member 7 and the rib-like projections 50 and 51 of the left and right moving member 6 are both inclined with respect to the traveling direction of the wheel 3, the piece member 7 and the left and right moving member 6 are included. Are engaged with each other via inclined surfaces 88 and 89.
[0033]
Since the width of the piece member 7 is equal to the width of the gap portion 17 of the case member 2 as described above, the piece member 7 does not have a degree of freedom in the left-right direction (based on the traveling direction of the wheel 3). The piece member 7 is mounted in the groove portion 40 of the left and right moving member 6 and slides between two horizontal and parallel planes of the left and right moving member 6. Therefore, the piece member 7 has no degree of freedom in the vertical direction and can move only in the direction along the traveling direction of the wheel 3.
[0034]
A screw 80 is inserted into the screw hole 70 of the piece member 7. As shown in FIG. 4, the screw 80 is rotatably attached to the hole 25 of the case member 2 and is integrally attached in the axial direction. Further, a washer 82 and a spring 83 are interposed between the head 81 of the screw 80 and the piece member 7, and the piece member 7 is always pressed toward the wheel 3 side.
[0035]
Next, the function of the door cart apparatus 1 of this embodiment is demonstrated. The door pulley apparatus 1 of this embodiment is attached to the lower part of the sliding door which is not shown in figure. That is, a notch is formed in the lower part of the sliding door, and the wood screw 85 is inserted into the mounting hole 18 from the operation side wall 11 side and fixed to the sliding door as shown in FIG. Therefore, in the door cart apparatus 1 of this embodiment, in the state attached to the sliding door, the operation side side wall 11 of the door cart apparatus 1 is exposed to the end surface of a sliding door. Therefore, in the door cart apparatus 1 of this embodiment, in the state attached to the sliding door, the screw 72 of the front-back moving member 8 exposed from the operation side wall 11 and the screw 80 inserted through the piece member 7 can be operated. .
[0036]
And in the door machine apparatus 1 of this embodiment, the wheel 3 can be raised / lowered up and down, and the height of a wheel can be changed by operating the screw | thread 72 of the front-back moving member 8. FIG. That is, when lowering the wheel 3 to raise the sliding door, the screw 72 is rotated in the “up” direction (left rotation) described in FIG. 1C from the state shown in FIG. As a result, the nut 73 moves to the left side of the drawing, pushes the cut portion 38 of the wheel support portion 5 to the left side of the drawing, and tilts the wheel support portion 5 downward about the pin 77. As a result, the exposure amount of the wheel 3 from the case member 2 increases, and the wheel 3 moves downward. Further, as the wheel 3 descends, the sliding door rises.
[0037]
Furthermore, in the door pulley apparatus 1 of this embodiment, the wheel 3 can be moved right and left with respect to the traveling direction by rotating the screw 80 inserted through the piece member 7, and the sliding door can be moved right and left.

Rotate in the “left” direction described in (c). Here, the piece member 7 that engages with the screw 80 has a width equal to the width of the inner surface of the case member 2, and is sandwiched between the groove portions 40 of the left and right moving member 6, so that the movement in the vertical and rotational directions is restricted. Therefore, the piece member 7 is drawn toward the head side (operation side wall 11 side) of the screw 80 as shown in FIG. On the other hand, since the grooves 67 and 68 provided in the piece member 7 are engaged with the groove portion 40 of the left and right moving member 6 via the inclined surfaces 88 and 89, the left and right moving member 6 is in contact with the inclined surfaces 88 and 89. And move in the lateral direction (based on the traveling direction of the wheel 3).
[0038]
Here, in the door cart apparatus 1 of this embodiment, since the piece member 7 is propelled by the screw 80, the moving amount of the piece member 7 with respect to the rotational operation amount of the screw 80 is small. Furthermore, in the door machine 1 of this embodiment, since the piece member 7 and the left-right moving member 6 are engaged via the inclined surfaces 88 and 89, the movement of the left-right moving member 6 with respect to the movement of the piece member 7 is slight. is there. Therefore, in the door roller apparatus 1 of this embodiment, the rotation amount of the screw 80 can be ensured by the synergistic effect of the reduction of the movement amount by the action of the screw 80 and the reduction of the movement amount by the inclined surface. That is, in the door roller apparatus 1 of this embodiment, when the wheel 3 is moved in the left-right direction, the allowance for rotation of the screw 80 is large. Therefore, the door machine 1 of this embodiment can perform fine adjustment of the wheel 3 in the left-right direction. Moreover, since the operation amount of the screw 80 with respect to the movement amount of the wheel 3 is large, when the wheel 3 is moved, the force required for the rotation of the screw 80 is light. Therefore, the door roller device 1 of the present embodiment can easily finely adjust the wheel 3 in the left-right direction.
[0039]
In the embodiment described above, a groove is provided on the piece member 7 and a protrusion is provided on the left and right moving member 6. However, a protrusion may be provided on the piece member 7 and a groove may be provided on the left and right moving member 6.
[0040]
【The invention's effect】

[0041]
In particular, in the door cart apparatus according to the second and third aspects, the relative movement between the piece member and the left and right moving member becomes positive, and the wheel can be moved in either the left or right direction.
[0042]
According to the fourth aspect of the present invention, a screw is adopted as the piece moving means, and the piece member is linearly moved by rotating the screw. Therefore, the operation amount can be increased with respect to the movement amount of the piece member. The door roller device of the present invention can secure a larger operation amount by combining the operation amount increasing function by the action of the inclination and the operation amount increasing function by the screw. Therefore, the position adjustment of the wheel in the left-right direction becomes extremely easy.
[0043]
